Aggregation-induced emission of siloles

Abstract

Recent advances in the structure–property relationship decipherment and luminescent functional materials development of AIE-active siloles are reviewed.

Marriage of heavy main group elements with π-conjugated materials for optoelectronic applications

“…In AIE, molecular rotations that normally facilitate non-radiative decay in the excited state are suppressed by the aggregationinduced restriction of molecular motion. 50 Accordingly a large number of silole analogues have been prepared for applications such as LED development, two-photon bioimaging and the sensing of analytes. [50][51][52][53] Herein we will describe key advances in the domain of formally conjugated heterocycles containing Ge, Sn and Pb.…”

‘Aggregation induced emission’ active iridium(iii) complexes with applications in mitochondrial staining

“…Worldwide many researchers have been working enthusiastically on the design and synthesis of new AIE materials and their applications. [17][18][19] In spite of all these efforts, the mechanism behind AIE is only partially understood and a vivid debate is still ongoing in the literature. The eld has been recently reviewed by Tang and co-workers.…”

Intramolecular charge transfer induced emission from triphenylamine-o-carborane dyads

“…[18][19][20][21][22][23][24][25][26] We have recently explored a series of ICT-emissive organic materials and carborane-based phosphorescent iridium(III) complexes that have been successfully applied in optoelectronic devices and cellular bioimaging. [27][28][29][30] Since 2001, various working mechanisms based on AIEactive materials have been proposed, including conformational planarization, 31 J-aggregate formation, 32 E/Z isomerization, 33 and excited state intramolecular proton transfer (ESIPT), [34][35][36][37] restriction of intramolecular rotations (RIR), 31 restriction of intramolecular vibrations (RIV) 32 and restriction of intramolecular motions (RIM). 34 For o-Cab-based materials, when the aromatic plane is perpendicular to the C1-C2 bond in oCab, the donor-acceptor interactions can be signicantly enhanced.…”
