(1-4) From a fundamental point of view, knowledge of molecular two-photon spectra and structure/property relationships are also important for a more complete understanding of the third order polarizabilities of conjugated molecules. However, very little is known or understood about two-photon states and spectra of conjugated molecules or how they correlate with structure. We have observed large two-photon absorptivities in bis-donor diphenylpolyene derivatives, that appears to be correlated to simultaneous charge transfer from the end groups to the pi-conjugated bridge in the molecule. These molecules are also excellent photoexcitable electron donors that can initiate charge-transfer reactions. In initial applications of these materials we have demonstrated their use in two-photon initiation of polymerization and optical limiting.","PeriodicalId":378320,"journal":{"name":"Organic Thin Films for Photonics Applications","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125007799","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}

It is believed that the electro-optic activity of workhorse NLO chromophores (e.g., DANS and Disperse Red) are of insufficient magnitude to be viable candidates for commercial device-quality materials.1 Consequently, much effort has been directed in the past few years toward the development of chromophores with device-quality magnitudes of molecular optical nonlinearities. Unfortunately, the translation of these so-called high-β chromophores to the expected bulk electro-optic activities in polymers generally has not been achieved. Recently, we have shown that this lack of electro-optic activity is due primarily to strong intermolecular electrostatic interactions between chromophores, which tend to align the chromophores in an antiparallel fashion, resulting in no net polar asymmetry in the bulk material.2,3","PeriodicalId":378320,"journal":{"name":"Organic Thin Films for Photonics Applications","volume":"121 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115200814","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}

The droplets were mostly micro-sized. Our aim, however, is to make use of nano-sized LC droplets for active optical devices such as optical switches or tunable filters. The surfaces of nano-sized LC droplets are too small to scatter light, so the total intensity of transmitted light is not changed, but the phase or polarization can be controlled by the birefringence generated by the response of nano-sized LC droplets to an electric field shown in Figure 1. There have been only a few works(4) including ours,5) which have similar aims. We have already reported the preparation of droplets about 50 nm in diameter and shown they respond to an electric field. In this work, we prepared the polymers containing nano-sized LC droplets by various conditions and measured their electro-optic effect, propagation loss, and response time.","PeriodicalId":378320,"journal":{"name":"Organic Thin Films for Photonics Applications","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122090987","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}
