To make a molecular design of efficient indoline dyes, fluorescence lifetimes should be longer than ca. 0.8 ns in chloroform, in addition to suitable HOMO and LUMO levels and bathochromic UV-vis absorption bands.

The novel near-infrared organic dyes were designed for use in plastic-substrate dye sensitized solar cells. As a result, η of 5.76% was achieved.

An indoline dye having both α-cyanoacrylic and rhodanine acetic acid anchor groups at the acceptor moiety exhibited improved stability upon fluorescence lamp irradiation.
