苉

苉用途

1.Kubozono等人曾经报道使化合物苉对场效电晶体（FETs）的有效改良。FETs 活性层中加入化合物1结果导致场效应迁移值(μvalue)为1.1cm2/Vs. 放置70个小时过后μvalue上升至1.75 cm2/Vs.这个结果表明改良后的场效应晶体管是一个O2-辅助设计,针对氧气具有稳定性.

2. Kubozono等人报道苉与碱金属钾、铷等结合后的超导性。当苉掺3.3当量(基于1)钾时T_e (超导转变温度)是18K(-255℃). 作为一个简单典型的有机化合物这个值是最高的.

相对于无机化合物来说，这些有机化合物具有很多的优势，比如说灵敏性, 透明度和低毒性。预计化合物苉将会应用在半导体和超导体研究领域中。

Comparative carcinogenicity of picene and dibenz[a,h]anthracene in the rat.

Biochem. Biophys. Res. Commun. 290(1) , 275-9, (2002)

Early carcinogenicity tests found no evidence of activity for picene but found considerable initiating and carcinogenic activity for dibenz[a,h]anthracene (DBA). More recent investigation suggested th...

Tracer-based source apportionment of polycyclic aromatic hydrocarbons in PM2.5 in Guangzhou, southern China, using positive matrix factorization (PMF).
