专利号:US-6184168-B1 优先权日:1997-09-22 标题:Synthesis of 1,4-trans-polybutadiene using a lanthanide organic acid salt catalyst 发明人:LYNCH THOMAS J 权利人:BRIDGESTONE CORP 摘要:The invention provides a catalyst composition, comprising: (a) an organolithium compound; and, (b) an organic acid salt of lanthanide series element; wherein: (1) only components (a) and (b) are required to promote the synthesis of 1,4-trans-polybutadiene; (2) the ratio of component (a) to component (b) is selected to maximize formation of the trans structure of said 1,4-trans-polybutadiene; and, (3) components (a) and (b) are selected for enabling further diblock synthesis. The invention further contemplates a process for using the catalyst to synthesize 1,4-trans-polybutadiene and other polymers and copolymers having trans configuration in the conjugated diene monomer contributed units.
专利号:US-2024324437-A1 优先权日:2023-03-22 标题 :Tunable polymer transport materials for application in perovskite solar cells 发明人:SELLINGER ALAN; ASTRIDGE DANIEL; LEVIN JACOB 权利人:COLORADO SCHOOL OF MINES 摘要:Polymer transport materials for application in perovskite solar cells capable of being tuned or manipulated to achieve desired properties, are provided herein. The present disclosure is directed to methods, systems, and compositions for achieving polymer transport materials (i.e., hole transport materials (HTMs)) with desirable properties such as solution processability, energy level tuning (i.e., adjusting), high thermal properties, tunable (i.e., adjustable) wettability, and perovskite defect passivation. In some aspects of the present disclosure, the synthesis of such HTMs may be implemented via relatively simple and inexpensive processes.
