NOVEL APPLICATIONS OF INDOLOINDOLE AND INDOLOQUINOLINE DYES |
摘要 |
A novel type of dye systems comprises a selection of 10H-indolo[1,2-a]indole compounds (henceforth abbreviated as IO compounds) and (5H,7H)-indolo[1,2-a]quinoline compounds (henceforth abbreviated as IQ compounds) showing a solvatochromic effect and exhibiting strong fluorescence in a variety of materials such as polypropylene, polyethylene, oils, various solvents, emulsions. Also disclosed are various methods how the IO/IQ compounds can be administered, especially how they can be produced and administered in situ from a precursor, responding to external stimuli such as enzyme activity, temperature and so forth. The response of a precursor to external stimuli can also be used to determine the presence or absence of such stimuli. |

1. Use of a compound having the general formula (Ia): or (Ib): wherein X is O, NH or S R1, R2, R3, R4, R5, R6, R7, R8, R9, R10 and R11 are independently selected from the group consisting of hydrogen; C1-4 alkyl; C1-4 alkoxy; fused or linearly connected aryl; fused or linearly connected heteroaryl; halogen; cyano; nitro; formyl and optionally substituted amino, carboxy, carbonyl, hydroxyl and sulfonyl as a dye in a low-polarity host with a room temperature dielectric constant ∈≦10.0. |
