  摘要：

  制备了在6,13位被芳基取代的并五苯衍生物，并研究了它们的电子性质以及与氧的光加成反应。被2-噻吩基和苯基取代的并五苯衍生物在光照下与溶液中的氧反应，得到其内过氧化物。这些一阶动力学常数经评估为1.5×10 -3  s -1和2.7×10 -3  s -1。具有五氟苯基的并五苯衍生物在溶液中相对稳定。具有2-噻吩基的内过氧化物的热解和光解在溶液中得到并五苯衍生物，其产率分别为30％和44％。另外，研究了内过氧化物薄膜的紫外线照射（254 nm），这表明并五苯衍生物的复制。

  摘要：

  并五苯具有优异的半导电特性，但在有机薄膜晶体管（OTFT）中的实际应用引发了诸多问题，主要由其对氧气的敏感性和极低的溶解度所致。为了解决使用并五苯所涉及的问题，在6位和13位引入了不同的芳基取代基。对于富电子芳基取代基，并五苯环系的形成可能伴随着起始的二氢并五苯二醇重排为13,13′-二取代的并五苯-6-酮。此外，还制备了6-单取代的并五苯。

  日期：——

  Iodination of zirconacyclopentadiene derivative gave diiododiene derivative. The product was lithiated with t-BuLi and treated with diiodonaphthalene successively to afford 6,13-bis(trimethylsilyl)-5,14-dihydropentacene. A 6,13-diiodo-5,14-dihydropentacene was synthesized by iodination of 6,13-bis(trimethylsilyl)-5,14-dihydropentacene with ICl. This diiododihydropentacene was used for the introduction of substituent at 6 and 13 positions by the cross-coupling reactions with Pd catalyst. After aromatization by a combination of DDQ and gamma-terpinene or triethylamine, 6,13-disubstituted pentacene derivatives were synthesized.

  Two series of new oligothiophene-pentacene hybrid compounds were successfully synthesized and characterized, which consist of pentacene and anthradithiophene skeletons modified by different oligothienyl groups at 6,13 sites or 5,11 sites, respectively. Their optical, thermal, and electrochemical properties show regular variations with the length change of the side groups. These materials exhibit much higher solubility and significantly improved thermal and photooxidation stabilities compared with unmodified pentacene and anthradithiophene.

  This study explores the assembly in the crystalline state of a class of pentacenes that are substituted along their long edges with aromatic rings forming rigid, cruciform molecules. The crystals were grown from the gas phase, and their structures were compared with DFT-optimized geometries. Both crystallographic and computed structures show that a planar acene core is the exception rather than the rule. In the assembly of these molecules, the phenyl groups block the herringbone motif and further guide the arrangement of the acene core into higher order structures. The packing for the phenyl-substituted derivatives is dictated by close contacts between the C-H's of the pendant aromatic rings and the carbons at the fusions in the acene backbone. Using thiciphene substituents instead of phenyls creates cofacially stacked acenes. In thin films, the thiophene-substituted derivative forms devices with good electrical properties: relatively high mobility, high ON/OFF ratios, and low threshold voltage for device activation. An unusual result is obtained for the decaphenyl pentacene when devices are fabricated on its crystalline surface. Although its acene cores are well isolated from each other, this material still exhibits good electrical properties.
• Increased photooxidation stability of pentacene derivatives linked with aromatic groups for OTFTs

  Pentacene derivatives linked with aromatic groups at the 6,13-positions have been synthesized and characterized for their photooxidation properties. They exhibit high solubility which provides low-cost solution deposition methods. However, most of them are highly susceptible to photooxidation in solution determined with a few minutes of their half-life time under ambient conditions, practically precluding them from solution fabrication applications. Interestingly, their photooxidation stability can be significantly increased by blocking out light. The thin film transistor device for 3,4,5-trifluorophenyl-substituted pentacene (2c) showed the highest mobility of 1.1 x 10(-2) cm(2) V-1 s(-1) with the threshold voltage of 20 V when it was prepared in the dark condition.
