The reaction of azaheterocyclic enamines with acrylamide was employed for the preparation of novel fluorescent scaffolds possessing a benzo[e]indoline moiety. Reaction of 3-substituted 2-methylidene-1H-benzo[e]indole with acrylamide gave rise to spiro[ben

The invention provides a series of novel asymmetric squarine micromolecules, and an application thereof. By introducing different electricity-rich aromatic units in two ends of a squaric acid four-membered ring as donor units, a series of low narrow-gap asymmetric squarine micromolecule photovoltaic materials are designed and synthesized. The series of the low narrow-gap asymmetric squarine micromolecule photovoltaic materials have strong absorption in visible and near-infrared light regions; absorption spectra cover400-900 nm; and HOMO and LUMO of the series of the low narrow-gap asymmetric squarine micromolecule photovoltaic materials can match well with energy levels of an acceptor material PCBM to obtain a high open-circuit voltage. The compounds have good solubility and film-forming property, so that the compounds can be applied in bulk hetero-junction organic solar cells processed by low-cost solution. Performances of the organic solar cells with asymmetric squaric acid macromolecules as donor materials can reach an open-circuit voltage Voc=0.72-1.05 V, a short-circuit current Jsc=8.80-12.67 mA/cm, a fill factor (FF)=0.38-0.55, and photoelectric conversion efficiency (PCE)=2.41-6.10%.
