NIPPON KAGAKU KAISHI, 1988 ピリジン中での酸の解離機構を解明する目的で,ピリジンを溶媒としてニトロフェノール類の電気伝導度測定およびこれらのカリウム壇の溶解度測定を行なった。酸(HA)の解離としては,単純イオン対の解離平衡とホモ共役イオン(HA2-)の生成平衡を考え,単純イオン対の熱力学的解離定数およびホモ共役生成定数を決定した。酸の解離定数はニトロ基の置換数に比例して大きくなり,酸の強さの序列は,ピクリン酸>2,4-ジニトロフェノール(2,4-DNP)>2,6-DNP>2,5-DNPおよびp-ニトロフェノール(p-NP)>ο-NP>m-NPであった。メタ位にニトロ基が置換したフェノールは,解離が低いばかりでなくホモ共役体を形成しやすく,ピクリン酸や2,4および2,6-DNPはほとんどホモ共役体を形成しないことが認められた ...

Is the Quantum Melting of a Polaron Wigner Crystal an Insulator-to-Superconductor transition ?
, 2000 On examining the stability of a Wigner Crystal (WC) in an ionic dielectric, two competitive effects due to Polaron formation are found to be important: (i) the screening of the Coulomb forces which destabilizes the crystal, compensated by (ii) the ...
