PEGylated liposomal doxorubicin is a polymeric antitumor drug approved clinically by the Food and Drug Administration, but it has no essentially increasing efficacy compared to free doxorubicin (DOX) because of the slow release rate. In this paper, a near-infrared polymer was designed and encapsulated in liposomes to photothermally accelerate the release of DOX. This polymer loaded liposome provides a maximum absorption that covers the ideal phototherapeutic window between 800 and 850 nm, which ensures an efficient photothermal release of DOX as a nano drug for the delivery of photothermal and chemo-combined therapy in a highly efficient cancer treatment.

A series of random terpolymers comprising two electron deficient phenyl (PDPP) and thiophene (ThDPP)-capped diketopyrrolopyrrole (DPP) in conjugation with the electron-donating thiophene moiety are synthesised using Stille coupling. Their optical properties, energy levels, hole mobility, crystallinity and solar cell device performance can be systematically fine-tuned by controlling the molar ratio between ThDPP/PDPP (30/70, 50/50, 70/30, and 90/10) contents in the polymer backbone. Herein, we find that the crystalline properties and hole mobility of the terpolymer are enhanced by increasing ThDPP content in the polymer backbone. However, increasing PDPP content leads to low hole mobility and weak crystalline features. These characteristic features afford remarkable effect on the solar cell device performance. Bulk heterojunction (BHJ) solar cells are constructed by using these random terpolymers as donor materials and [6,6]-phenyl-C71-butyric acid methyl ester (PC71BM) as the acceptor. The best device performances are obtained for polymer P5T5P with the ThDPP/PDPP ratio of 50/50 and power conversion efficiency (PCE) of 2.9% due to balanced charge carrier mobility and optimized crystallinity in addition to good miscibility and favorable surface morphology with the fullerene acceptor. This study demonstrates that improved control of the crystallinity of the polymer donor through structural engineering can greatly help in improving device performance.

We have synthesized two novel dicyanovinylene-substituted DPP-oligothiophene semiconductors, DPP-4T-2DCV and 2DPP-6T-2DCV. In these materials, the combination of an extended oligothiophene conjugated skeleton with the strong electron-withdrawing DPP-dicya
