Unsymmetrical p‐Carborane Backbone as a Linker for Donor–Acceptor Dyads

Abstract

Fluorescent nanorods: Donor-acceptor dyads based on novel unsymmetrically disubstituted closo-1,12-dicarbadecaboranes have been prepared in a completely controlled manner by using a three-step procedure. Dyads with different donor-acceptor spacing were thereby obtained. Efficient energy transfer from the donor to the acceptor was determined in fluid solution at room temperature.

Twists and turns: Studies of the complexes and properties of bimetallic complexes featuring phenylene ethynylene and related bridging ligands

“…These subbands were therefore assigned to the three possible IVCT transitions in a mixed Rather, the EPR data are consistent with electron-exchange processes on the same time-scale as the measurement (10 8 -10 10 s -1 ). Similar phenomena have been observed 'three dimensional' aromatic character [235][236][237], the latter aspect of which has piqued curiosity in these cluster systems as a potential conduit for electronic effects across the cage [238][239][240][241][242][243][244][245]. [246] has made these compounds available for use in the preparation of diethynylcarborane bridged bi- [247,248] and polymetallic [244,245] complexes (Scheme 11).…”

Boron, aluminium, gallium, indium and thallium

“…76 Unsymmetrical 1,12 functionalised p-C 2 B 10 H 12 compounds were developed as an optically transparent and redox inert linker for joining different photoactive moieties. 77 2,2 0 -Bithiophene fused in a cisoid structure with o-carborane has lower HOMO and LUMO levels relative to 2,2 0 -bithiophene due to the inductive electron withdrawing effect of o-carborane. 78 The preparation of 8-iodo-1,2-dicarba-closo-dodecaborane was achieved from B 10 H 14 and used in the synthesis of 3,10-diiodo-1,2-dicarba-closo-dodecaborane.…”

Second-Order Nonlinear Optical Properties of Carboranylated Square-Planar Pt(II) Zwitterionic Complexes: One-/Two-Dimensional Difference and Substituent Effect

“…Carboranes are usually deemed as polyhedral boranes with one or more BH vertices being replaced by CH ones, recognized as three-dimensional inorganic benzene analogues. Indeed, they are termed as “superaromatic” and exhibit extraordinary thermal stability as well as unusual chemical reactivity such as electrophilic substitution, similar to that of planar aromatics. − Owing to their unique steric/electronic properties, many applications in drug design, − as well as in materials − and organometallic/coordination chemistry have been found. − And a growing interest has been directed toward the design and synthesis of complexes that combine carborane clusters and aromatic units. − Moreover, it has been reported that carboranes linked organic groups fulfill many requirements of optical luminescence and nonlinearity. − Thus, continuing our interest in the study of carborane complexes, ,− a new member of the family of high-performance NLO materials were discussed here.…”
