Solution‐processable polymers consisting of perylenediimide (PDI) acceptor moieties alternating with dithienothiophene (DTT), N‐dodecyl‐dithienopyrrole (DTP), or oligomers of these donor groups have been synthesized. We have, in addition to varying the donor, varied the N,N′ substituents of the PDIs. The thermal, optical, electrochemical, and charge‐transport properties of the polymers have been investigated
已合成了由per二酰亚胺(PDI)受体部分与二噻吩并噻吩(DTT),N-十二烷基-二噻吩并吡咯(DTP)或这些供体基团的低聚物交替组成的可溶液加工的聚合物。除了改变供体之外,我们还改变了N,N'PDI的取代基。已经研究了聚合物的热,光学,电化学和电荷传输性质。聚合物显示出从300到1000 nm的宽吸收,光学带隙低至1.2 eV。带隙随着供体嵌段共轭长度的增加或通过DTP取代DTT而减小。根据电化学数据估算,聚合物的电子亲和力在-3.87至-4.01 eV的范围内,并受供体部分的具体选择的影响很小,而估算的电离电势(-5.31至-5.92 eV)对聚合物更敏感。选择捐赠者。基于聚合物的底栅顶接触有机场效应晶体管通常表现出n沟道行为,电子迁移率高达1.7×10 –2 cm 2/ V / s和开/关比高达10 6;一种PDI-DTP聚合物是一种双极性传输材料,在空气中的电子迁移率为4×10 –4
Conjugated Polymers of Rylene Diimide and Phenothiazine for n-Channel Organic Field-Effect Transistors
chain and side chain structure and molecular weight have minor effects on the HOMO (−5.8 to −5.9 eV) and LUMO (−3.7 to −3.8 eV) levels of the polymers. n-Channelfield-effecttransistors with bottom-gate top-contact geometry based on these copolymers exhibit electron mobilities as high as 0.05 cm2 V–1 s–1 and on/off ratios as high as 105 in nitrogen, which are among the best reported for rylene diimide-based
通过Pd催化的Suzuki偶合聚合反应,设计了一系列基于phase二酰亚胺(PDI)或萘二酰亚胺(NDI)和吩噻嗪(PTZ)的新型n型共聚物。 -转移催化剂Aliquat 336.研究了主链,侧链和分子量对聚合物的热,光,电子和电荷传输性质的影响。Aliquat 336提高了分子量,并降低了聚合物的多分散指数。所有聚合物均表现出从300到900 nm的宽吸收。主链和侧链的结构以及分子量对聚合物的HOMO(-5.8至-5.9 eV)和LUMO(-3.7至-3.8 eV)水平影响较小。2 V –1 s –1的氮气中的开/关比高达10 5,在相同的测试条件下,这是基于二甲苯二酰亚胺基聚合物的最佳报道。
A photothermal agent can be used in both photoacoustic imaging (PAI) and photothermal therapy (PTT) applications. The photothermal agent can include a small molecule, organic compound and/or polymers with absorption in the near-infrared (NIR) interrogation window (700-900 nm). The compound can be a biocompatible organic nanoparticle (ONP). The photothermal agent can be administered to a patient to locate a tumor site in the patient using in vivo imaging techniques. Once the tumor site has been determined, the tumor site can be irradiated with near-infrared light to stop or inhibit the growth of the tumor.

the benzannulation of perylene diimides with the almost quantitative yield. The thermotropicbehavior was investigated using differential scanning calorimetry (DSC) and polarization optical microscopy (POM). The introduction of alkyl swallow-tail and alkoxy substituents facilitates thermotropic liquid crystalline behavior. The branching site of alkyl swallow-tail units at the α position and the longer

An insoluble thin film of a coronene diimide (CDI) derivative was fabricated from a soluble precursor of perylene diimide (PDI) by photoirradiation. We prepared a 1,7-diarylated PDI (TP-PDI) that can be converted into a coronene diimide (TP-CDI) derivative via a Scholl-type photocyclization reaction. This reaction was accompanied by structural changes from a twisted structure to a π-extended planar
