Research Abstract	ヘテロキノノイド共役系を持つ新規電子受容体としてヘテロTCNQ類の欠点である弱い電子受容能を改善するため中央のチオフェン環をベンゼン環に置換する構造修飾を行ったベンゾジオフェン環を持つ異性体化合物群(I,II,III)の合成に成功しCT錯体合成と物性評価を行った。いずれも電子受容能は大幅に改善され多くのドナーと高電導性CT錯体を与えた。また電子受容能が強くon-site Couomb反発が小さい優秀な電子受容体であるTANT(IV;R=H)に9,10-位をCl,CH_3S,n-C_8H_<17>S等の基で置換する構造修飾を行い欠点であった溶解性の低さを改善する事に成功し多くの高電導性CT錯体を得る事が出来た。一方電子供与体についてはPyreneと等電子構造のHeteroarene,syn-及びanti-NDT(V,VI;R=H)の合成に成功し硫黄原子導入による電子供与能改善の効果を確証すると共に高電導性CT錯体を得た。現在電子供与能と安定性の向上を目指しthiophene環のα-位に置換基を導入する修飾を試みている。またテルロフェンの二,三量体(VII,n=0,1)の合成に成功し物性について研究を進めている。更に二個のTTF分子を多重結合ヘテロ環等π-共役系で連結した系(VIII)の合成に成功し高電導性錯体合成等興味ある物性について研究を進めている。
