Controlling Morphology of Active Layer by Tuning coplanarity of the Centrality in Acceptor-Donor-Acceptor Small Molecules for Photovoltaic Application

Chinese Journal of Chemistry 2013年第11期31卷 1439-1448页

A series of acceptor-donor-acceptor alternative small molecules were synthesized containing electron-donating central building moieties of phenothiazine, 2,7-carbazole and thieno[3,4-b]thiophene and electron-accepting moie- ties of tetrazine on both sides. The various conformations of the central blocks, with the coplanarity in an order of phenothiazine〈2,7-carbazole〈thieno[3,4-b]thiophene, have an obvious influence on the optical, electrochemical property and the crystallinity of small molecule. In addition, the blend films between small molecule and （6,6）-phenyl-C6rbutyric acid methyl ester offered significantly various morphologies, changing from uniform sur- face to interpenetrated networks. As a result, the bulk heterojunction photovoltaic devices based on the three small molecules provided varied performance, and the highest coplanar molecule based device exhibited the best photo- voltaic performance.

Embedding pyridine units in acceptors to construct donor-acceptor conjugated polymers

引用

Chinese Chemical Letters 2019年第1期30卷 25-30页

作者： Zi-Yuan Wang Jie-Yu Wang Jian Pei Beijing National Laboratory for Molecular Sciences Key Laboratory of Bioorganic Chemistry and Molecular Engineering of Ministry of Education Key Laboratory of Polymer Chemistry and Physics of Ministry of Education Center for Soft Matter Science and Engineering College of Chemistry and Molecular Engineering Peking University

The development of donor-acceptor(D-A) conjugated polymers greatly promotes the device performance in organic electronics. Recently, the strategy of embedding pyridine units into D-A conjugated polymer backbones has attracted much attention due to the resulted lowered LUMO levels. In addition, the possible non-bonding interactions resulted from the nitrogen atoms also improve the coplanarity of the polymer backbones. All these factors have great contribution to enhance the device performance. In this review, we summarized the recent development of pyridine-embedded D-A conjugated polymers and their applications in organic field-effect transistors(OFETs).

A Machine Vision System for Ball Grid Array Package Inspection

引用

Journal of Shanghai Jiaotong university(Science) 2005年第2期10卷 139-142页

作者：夏年炯曹其新李杰 Research Inst. of Robotics Shanghai Jiaotong Univ. Shanghai 200030 China Center for Intelligent Maintenance Univ. of Wisconsin at Milwaukee Milwaukee WI 53211 USA

An optical inspection method of the Ball Grid Array package(BGA) was proposed by using a machine vision system. The developed machine vision system could get main critical factors for BGA quality evaluation, such as the height of solder ball, diameter, pitch and coplanarity. The experiment has proved that this system is available for BGA failure detection.
