In this article the systematic investigation on the NLO properties of Donor/Acceptor substituted branched chain organic chromophores, chalcones, using semi empirical method is presented. The nonlinear optical molecular static first hyperpolarizability (β) was found to be larger for Donor/Acceptor group substituted at para position than that of substitution of Donor/Acceptor group at meta and ortho position. For designing NLO materials with high β it is recommended to make substitution of Donor/Acceptor group at para position rather than meta and ortho position.","PeriodicalId":174448,"journal":{"name":"International Journal of Pure and Applied Physics","volume":"173 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115176429","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
