NEAR-INFRARED ABSORBING DYE, OPTICAL FILTER, AND IMAGING DEVICE

A near-infrared absorbing dye includes a compound represented by formula (A). Each of R11 to R14 is independently a hydrogen atom, a halogen atom, a hydroxyl group, or an alkyl, aryl or alaryl group. Each of pairs R11 and R12, R12 and R13, and R13 and R14 may combine with one another to form a monocyclic ring or a polycyclic ring in which from 2 to 4 rings are fused. Each of R15 and R16 is independently an alkyl or alaryl group. R15 and R16 may combine with one another to form a cyclohetero ring having from 5 to 10 members together with the nitrogen atom.

Synthesis of Annulated Anthracenes, Carbazoles, and Thiophenes Involving Bradsher-Type Cyclodehydration or Cyclization-Reductive-Dehydration Reactions

A conventional BF3·OEt2-mediated Bradsher-type cyclodehydration of 2-arylmethyl benzaldehydes in CH2Cl2 at room temperature gave polycyclic aromatic and heteroaromatic compounds. Alternatively, these compounds could be synthesized in better yields from 2-arylmethylbenzoic acids by triflic-acid-mediated cyclization followed by reductive dehydration.

Synthesis and characterization of naphth-annelated thiophene analogs

Synthesis of symmetrical and unsymmetrical naphth-annelated thienyl heterocycles has been achieved via thionation of hydroxyketones/diketones using Lawesson's reagent. Photophysical studies of 1,3-disubstituted naphtho[c]thiophene analogs are presented. Electro-oxidative behavior of these naphtha-annelated thiophenes are investigated using cyclic voltammeter.
