Photocurrent generation in an electrochemical cell with substituted metalloporphyrins

Electrochemical Properties and Electropolymerization of Tetrakis(para-aminophenyl)porphyrin in Dichloromethane

“…Электронный спектр хроматографически очищенного тетракис(пара-аминофенил)порфина соответствовал литера-турным данным: R f 0.71 (метанол). ЭСП (хлороформ) λ max нм (lg ε): 654 (4,00), 597 (3,82), 562 (4,14), 524 (4,15), 428 (5,53 …”

“…[4][5][6] Большое количество работ посвящено исследованию электрохимических свойств [7][8] и приме-нению порфиринов в качестве катализаторов, [9][10] свето-излучателей и рецепторов, единиц хранения заряда. [11][12][13][14][15] Электроды, покрытые электроактивными полиме-рами, могут применяться в энергонакопителях, фото-и хемосенсорах, электроанализе, в процессах связанных с переносом заряда. [16][17] Создание полимеров с заданными оптическими и электронными свойствами представля-ет значительный шаг вперед в создании электронных и оптико-электронных устройств таких, как органические светоизлучающие диоды, электрохромные элементы, солнечные батареи, органические тонкослойные транзи-сторы.…”

Spectroscopic and photoelectric studies of phthalocyanines in polyvinyl alcohol for application in solar energy conversion

“…Some porphyrins were the object of numerous investigations [5] and the ability of porphyrins and phthalocyanines to photocurrent generation when immersed in a specially constructed photoelectrochemical cell was presented [6,7,8]. In our laboratory a lot of attention is devoted to the construction and development of the photoelectrochemical cell as well as to the spectroscopic and photovotlaic studies of organic synthetic dyes as potential molecular material for application in solar energy devices [9,10,11,12].…”

“…In our previous papers we have investigated various synthetic porphyrins substituted with peripheral groups and complexed with metal dissolved in either nematic liquid crystal [9] or in liquid polyvinyl alcohol [10]. We have found that the intensity of photocurrent generated in the electrochemical cell depends on many factors: delocalization of π -system due to the variation in molecular structure, the type of metal incorporated in the centre of porphyrin ring, the peripheral group attached to the main molecular corn and solvent used as a medium for dyes.…”

“…We try to find the correlation between molecular structure of dyes and their photoactive properties which can be responsible for their ability to photocurrent generation. The comparison of data presented in this paper for Pc dyes with those for porphyrins [9,10] has been discussed. Vol.…”
