3,3′-Bithiophene

Two-photon fluorescent microporous bithiophene polymer via Suzuki cross-coupling.

A microporous bithiophene polymer (MBP) stable up to 460 °C was synthesized using bithiophene and biphenyl as building blocks through Suzuki cross-coupling. The as-obtained MBP product exhibits green fluorescence peaked at 530 nm, and most interestingly, a two-photon fluorescence was observable from MBP upon excitation by an 800 nm femtosecond laser.

The Optical Properties of CdSe Quantum Dot-Bithiophene Complexes

We studied the optical and electrochemical properties of four model oligomers M3, M5, M9 and M17, Fig. 1. We have performed extensive experimental and theoretical analyses of the M series oligomers in order to determine the oligomers that would be the best charge transfer partners for CdSe quantum dots with respect to spectral overlap and band level alignment. The steady-state absorption and fl...

Multifaceted strategy for the synthesis of diverse 2,2'-bithiophene derivatives.

New catalytically or high pressure activated reactions and routes, including coupling, double bond migration in allylic systems, and various types of cycloaddition and dihydroamination have been used for the synthesis of novel bithiophene derivatives. Thanks to the abovementioned reactions and routes combined with non-catalytic ones, new acetylene, butadiyne, isoxazole, 1,2,3-triazole, pyrrole,...

33 Visibility

In a geometric context, two objects are “visible” to each other if there is a line segment connecting them that does not cross any obstacles. Over 500 papers have been published on aspects of visibility in computational geometry in the last 40 years. The research can be broadly classified as primarily focused on combinatorial issues, or primarily focused on algorithms. We partition the combinat...
