Tetrakis{[(p‐dodecacarboranyl)methyl]stilbenyl}ethylene: A Luminescent Tetraphenylethylene (TPE) Core System

Abstract

Abstract:The synthesis and spectroscopic characterization of the first set of tetrakis{ [(p-dodecacarboranyl)methyl]-stilbenyl}ethylenes (TDSE), substituted either with a methyl or a phenyl group in the 2-position (C cluster ) of the ortho-carborane, are described. The complex absorption properties are elucidated by TD-DFT calculations, stressing the importance of through-bond conjugation. Enhanced conjugation and restric-

Improvement of Solid‐State Excimer Emission of the Aryl–Ethynyl‐o‐Carborane Skeleton by Acridine Introduction

“…Except for these materials, wide variety of solid‐state luminescent o ‐carboranes have been recently discovered. Thus, it can be said that o ‐carborane should be a versatile platform for designing advanced optoelectronic materials , , …”

Photoluminescence in m-carborane–anthracene triads: a combined experimental and computational study

“…But more interestingly, the fluorescence efficiency can be tailored by changing the substituent at the adjacent Cc position, which may cause either an enhancement of the emission quantum yield or a total fluorescence quenching in the case of aromatic substituents. [11][12][13][65][66][67][68][69] Anthracene is a very well-studied -conjugate system easy to functionalize and with remarkable intrinsic photophysical, photochemical and chemical properties, which make it and its derivatives ideal molecules to construct fluorophores, fluorescent probes, organic light-emitting transistors, among others. 70,71 Throughout the last years, some carboranyl-functionalized anthracene derivatives have been reported and their photoluminescence behaviour explored.…”

Carborane‐BODIPY Dyads: New Photoluminescent Materials through an Efficient Heck Coupling

“…Littke and Fu described in 2001 the Pd 2 (dba) 3 /Pd(P( t Bu) 3 ) 2 catalytic system in the presence of dicyclohexylmethylamine (Cy 2 NMe) as an effective tool for Heck reactions of aryl chlorides and aryl bromides, suitable for both harsh and mild conditions . The unusual effectiveness of the base, which was proven to provide a more active catalyst compared to other bases (such as Cs 2 CO 3 ), also made this versatile procedure efficient to introduce a variety of functional groups either on brominated and iodinated silicate cages (possessing similar characteristics to the carborane cluster) and on the carboranyl substrates of our interest –…”
