A near-infrared absorbing dye includes a compound represented by formula (A). Each of R
11
to R
14
is independently a hydrogen atom, a halogen atom, a hydroxyl group, or an alkyl, aryl or alaryl group. Each of pairs R
11
and R
12
, R
12
and R
13
, and R
13
and R
14
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 R
15
and R
16
is independently an alkyl or alaryl group. R
15
and R
16
may combine with one another to form a cyclohetero ring having from 5 to 10 members together with the nitrogen atom.

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]thiopheneanalogs are presented. Electro-oxidative behavior of these naphtha-annelated thiophenes are investigated using cyclic voltammeter.
通过使用Lawesson试剂对羟基酮/二酮进行硫磺化,已经完成了对称和不对称的萘环化噻吩基杂环的合成。提出了1,3-二取代萘[ c ]噻吩类似物的光物理研究。使用循环伏安法研究了这些石脑油-退火噻吩的电氧化行为。
