Disclosed are conjugated polymers based on terthiophene. Such polymers exhibit good solubility and great solution processibility, and that enable highly efficient OPVs.

Polymer embodiments comprising nanohoop-containing polymer backbones are described, along with methods of making and using the same. The polymer embodiments exhibit unique radial and linear conjugation and can be used in a variety of devices, such as electronic and/or optoelectronic devices.

Described are conjugated polymers and conjugated polymer nanoparticles formed therefrom. The conjugated polymers and conjugated polymer nanoparticles have a maximum emission of light that occurs within a tissue transparent window of the electromagnetic spectrum. These emission properties are particle-size independent. The sizes of the conjugated nanoparticles are controlled by altering the concentration of the conjugated polymer used to make conjugated polymer nanoparticles. Also described are methods of making conjugated polymer nanoparticles that have larger sizes than have been traditionally reported, involving a modified reprecipitation approach. The conjugated polymers and/or conjugated polymer nanoparticles can be used as fluorescent probes in biological imaging.

A compound having the following formula:

##STR00001##

which can also be embedded into a conjugated oligomeric of polymeric backbone, is proposed for optical and electro optical applications.

The present specification provides a copolymer and an organic solar cell including the same.

The present disclosure provides a white-light block polymer, an ink composition, and a manufacturing method thereof. The white-light block polymer makes it only necessary to print one ink when using inkjet printing, thereby simplifying inkjet printing processing and meanwhile preventing a crosstalk problem of pixels having different colors of light. The present disclosure makes the ink composition suitable for inkjet printing by properly mixing the white-light block polymer, an organic solvent, a surface tension modifier, and a viscosity modifier in a suitable ratio.

A novel AB-type copolymer for use in organic photovoltaics. The AB-type copolymer comprises a unit A, where the unit A is ##STR00001##
where R.sub.1 is a carbon chain from about 1 to about 30 units and where Y is selected from CN, F and Cl. The B unit of the AB-type copolymer is selected from is selected from: ##STR00002## ##STR00003##
wherein
X.sub.1, X.sub.2, X.sub.3, and X.sub.4 are independently selected from the group consisting of: H, Cl, F, CN, alkyl, alkylthiol, alkoxy, ester, ketone, amide and aryl groups.
