Photoelectrocatalysis to improve cycloreversion quantum yields of photochromic dithienylethene compounds.
An open and shut case: photoirradiation of the 9-mesityl-10-methylacridinium ion, which acts as a photoredox catalyst, evoked catalytic cycloreversion of the photochromic 1,2-dithienylethene (DTE) compounds with one order of magnitude enhancement in quantum yields. Mechanistic studies revealed that the back electron transfer and electron transfer from the neutral closed form of DTE compounds to...
متن کاملVibrational coherence transfer in an electronically decoupled molecular dyad
The ring opening of a dithienylethene photoswitch incorporated in a bridged boron-dipyrromethene - dithienylethene molecular dyad was investigated with ultrafast spectroscopy. Coherent vibrations in the electronic ground state of the boron-dipyrromethene are triggered after selective photoexcitation of the closed dithienylethene indicating vibrational coupling although the two moieties are elec...
متن کاملA new photochromic tetrahydroindolizine.
The title compound, dimethyl 10b'-(4-fluorostyryl)-8',9'-dimethoxy-4-nitro-5',6'-dihydrospiro[9H-fluorene-9,1'(10b'H)-pyrrolo[2,1-a]isoquinoline]-2',3'-dicarboxylate, C38H31FN2O8, is a new photochromic tetrahydroindolizine. One of the C-C bonds at the spiro C atom is very long [1.630 (2) A], thus explaining the photochromic behaviour.
متن کاملIntergenerational Learning Program: A Bridge between Generations
One of the goals of education can be considered the transfer of knowledge, skills, competencies, wisdom, norms and values between generations. Intergenerational learning program provide this goal and opportunities for lifelong learning and sharing knowledge and experience between generations. This review aimed to investigate the benefits of this program for the children and older adult and its ...
متن کاملPhotochromic one-dimensional nanostructures based on dithienylethene: fabrication by light-induced precipitation and reversible transformation in the nanoparticle state.
A convenient protocol has been developed to fabricate one-dimensional nanostructures of a photochromic molecule cis-l,2-dicyano-l,2-bis(2,4,5-trimethyl-3-thieny1)ethene (CMTE). Light-induced self-assembled nanorods and nanowires of the colored form were obtained in situ under UV light irradiation in aqueous dispersion and redissolved under green light. Reversible and fatigue-resistant optical s...
