Trosolwyg
The main scheme of our research is to explore exciton/charge generation and transport within molecular assemblies, where novel properties emerge upon chromophore association. Such work allows for a better understanding of these processes in truly complex, multi-component structures in the macroscopic world. Fundamentally, the ground and excited-state carrier dynamics are controlled by the chemical potential, which is a function of atomic composition, intermolecular interaction, orientation, and even spatial density. Thus, our primary efforts have been focused on the development of methods to prepare an ensemble of molecules with tailored molecular properties with high spatial (0D to 3D) precision of the assemblies. Our approach will go beyond the conventional covalent or supramolecular synthetic methods and will exploit, for instance, the curvature of the substrate or external stimuli to modulate the local chemical potential. Parallel to this endeavour, due to the importance of the microscopic structure, we will also be applying imaging technologies with high spatial resolution, such as (conductive) AFM and (in situ) SEM/TEM for the solid samples.
We are currently working on the following topics:
• Heavy metal-free organic redox photosensitizer/photocatalyst
• Organic room-temperature phosphors
• Functional porous materials
• New reaction development and mechanistic investigation

● Metel Trwm Di-fetel Organig Redox Photosensitizer / Photocatalyst
Mae trawsnewid cemegol ysgafn yn hollbresennol o ran natur ac yn ganolog i swyddogaeth llawer o brosesau bywyd. Yn yr adweithiau hyn, mae pŵer solar cynaliadwy yn actifadu swbstradau i ffurfio'r canolradd ynni uchel, gan arwain at gynhyrchion newydd neu dargedau diraddio na ellir eu cyflawni fel arall. Er mwyn galluogi posibilrwydd o'r fath o dan amodau ysgafn, mae angen cyfranogiad ffotoensitizer sy'n amsugno golau. Er bod y dewis traddodiadol o ffotoensitizers wedi'i gyfyngu i ddeunyddiau trawsnewid-metel, rydym yn datblygu dewisiadau amgen organig di-fetel yn seiliedig ar ystyriaethau cemegol cwantwm sylfaenol. Rydym yn cyflwyno grwpiau swyddogaethol bach i liwio masnachol i ragfarn y cyfeiriadedd orbitol a'r dosbarthiad dwysedd electron. Mae'r strategaeth gyffredinol hon yn gwarantu ffurfio tripled cyflym gydag ychydig iawn o golli ynni o'r broses troi troelli, gan ddarparu ffotoensitizers teilwra ar gyfer adweithiau cemegol penodol.
● Ffosfforyddion tymheredd ystafell organig
Bydd datblygu deunyddiau organig yn unig sy'n arddangos ffosfforoleuedd tymheredd ystafell (RTP) yn ehangu blwch offer ffosfforyddion anorganig ar gyfer cymwysiadau delweddu, synhwyro neu arddangos. Ar y naill law, mae'r dasg heriol hon yn gysylltiedig â chynnyrch ffurfio isel gwladwriaethau triped ffosfforoleuol mewn deunyddiau organig; Ar y llaw arall, mae wedi'i wreiddio'n ddwfn yn y ddeinameg strwythurol gymharol gyflym yn y moleciwlau cyffrous, gan arwain at afradu ynni anradiadol. Er mwyn mynd i'r afael â'r materion hyn, rydym yn cyflwyno grwpiau swyddogaethol a all hwyluso ffurfio tripledi a chymryd rhan mewn rhyngweithiadau nad ydynt yn cofalent ar yr un pryd. Mae'r rhyngweithiadau amlfalent a chyfeiriadol nad ydynt yn cofalent yn cyfyngu'r symudiadau moleciwlaidd ac yn gwneud y broses RTP yn ffafriol yn cinetig. At hynny, mae gennym ddiddordeb mewn nodi'r symudiadau moleciwlaidd critigol y mae angen eu hatal trwy fodelu moleciwlaidd a pheirianneg strwythurol. Bydd gwybodaeth o'r fath yn awgrymu'r strategaeth fwyaf effeithlon i weithredu rhyngweithiadau nad ydynt yn cofalent ar gyfer cydffurfiad cyflwr cyffrous a rheolaeth electronig.
● Deunyddiau Porous Swyddogaethol
Gan fod priodweddau'r rhan fwyaf o ddeunyddiau bywyd go iawn yn ffwythiant o faint o agregiad moleciwlaidd, rydym yn manteisio ar lwyfan pensaernïaeth fandyllog i fodiwleiddio'r rhyngweithiadau rhyngfoleciwlaidd yn y cyfnod cyddwyso. Gellir gwahanu'r cydrannau moleciwlaidd yn bell oddi wrth ei gilydd, gan gynnal yr ymddygiad monomerig fel amsugno golau neu adweithedd cemegol. Gall y cydrannau hefyd yn cael eu trefnu drwy stacio aromatig. Yn y sefyllfa hon, mae eiddo newydd yn dod i'r amlwg oherwydd rhyngweithio rhyngfoleciwlaidd cryf; Yn aml, gwelir gwell cyffro a symudedd electronau neu gyfryngu ynni uchel sefydlog. Mae tiwnio strwythurol dibynadwy rhwng y ddau eithaf hyn o'r pwys mwyaf; Gellir disgwyl deunyddiau arloesol o gynulliadau moleciwlaidd gyda gwisg ofodol neu nodweddion strwythurol / cyfansoddiadol graddiant. Yn ogystal, mae gennym ddiddordeb arbennig mewn datblygu dulliau i greu solidau mandyllog crisialog trwy gemeg nad yw'n cofalent neu bolymerau amorffaidd gydag esgyrn cefn cynhenid nad ydynt yn planar ac nad ydynt yn stacio. Mae methodolegau o'r fath yn caniatáu ar gyfer rhwyddineb cynhyrchu màs ac ailgylchadwyedd y deunyddiau hyn.
● Datblygiad Adwaith Newydd ac Ymchwiliad Mecanistaidd
Mae cyfansoddion sylffwr organig wedi'u gohirio ers amser maith fel yr allwedd i gysylltu'r anorganig (clystyrau H2S, SO2 a haearn-sylffwr) a chemeg organig o'r oes prebiotig, y mae Natur yn cyflawni syntheses cymhleth a metaboledd sy'n hysbys hyd yn hyn. Mae eu hyblygrwydd yn tarddu o'r egni bond cymedrol a gwladwriaethau rhydocs cyfoethog yn y cemegau hyn. Felly gallant wasanaethu fel catalyddion neu gyfryngwyr i hwyluso trawsnewidiadau effeithlon sydd fel arall yn anodd eu cyflawni. Gyda chysylltiadau cryf â'n rhaglenni ymchwil eraill, mae gennym ddiddordeb mewn datblygu dulliau ffurfio bond sy'n cynnwys, ond heb fod yn gyfyngedig i, thiocarbonyl, thioester a thioamide functionalities. Rydym yn cymhwyso'r dulliau hyn ar gyfer synthesis cromosomau newydd, polymereiddio effeithlon a chyd-gysylltiad bioorthogonol gyda dealltwriaeth fecanistaidd glir o'r adweithiau hyn.

Bywgraffiad
Ganwyd Yi-Lin yn Taipei a derbyniodd ei B.S. mewn Cemeg o Brifysgol Genedlaethol Taiwan (2005) dan hyfforddiant yr Athro Tien-Yau Luh. Ar ôl y gwasanaeth milwrol, symudodd i'r Swistir i ddilyn ei raddau M.Sc. (2008) a Ph.D. (2012) yn ETH Zürich gyda'r Athro François Diederich. Yn ETH, bu'n ymwneud ag ystod eang o brosiectau organig corfforol yn amrywio o ymchwiliad mecanistig syntheses math clic i systemau ffoto-switchable ar gyfer anwythiad crisial hylif cholesterig. Cydnabuwyd ei waith graddedig gan Ysgoloriaeth Ragoriaeth ETH Zurich, Novartis M.Sc. Cymrodoriaeth, a Chronfa Ysgoloriaeth Diwydiant Cemegol y Swistir.
Yn dilyn ei Ph.D., dyfarnwyd iddo Gymrodoriaeth Sefydliad Gwyddoniaeth Cenedlaethol y Swistir (SNF) i ddechrau ei ymchwil ôl-ddoethurol (2012) yng ngrŵp yr Athro Michael Wasielewski ym Mhrifysgol Northwestern, lle cafodd ei ddyrchafu'n Athro Cynorthwyol Ymchwil (2014) ac Athro Cyswllt Ymchwil (2017) mewn Cemeg. Yn Northwestern, cymerodd y dulliau synthetig a sbectrosgopig ar yr un pryd i archwilio'r cydadwaith rhwng y nanostructures hunan-cynulliad a deinameg electron/sbin / egni cyflwr cyffrous bioleg- a deunyddiau ffotofoltäig-berthnasol.
Cymerodd Yi-Lin swydd Darlithydd mewn Cemeg Deunyddiau ym Mhrifysgol Caerdydd ym mis Ionawr 2019.
