These results are not only extremely relevant for applications\u0000requiring a custom-tailored ENZ region in the visible but also provide important novel\u0000information on how molecular aggregation affects the ENZ properties. In particular, based on our findings, we stress that J-aggregate is not always a mandatory molecular assembly for\u0000obtaining a strong ENZ response. Instead, molecular aggregates with the size of a few\u0000nanometers resulting in strong molecular interactions (i.e. Davydov splitting of the lowest\u0000transition in energy) are required to achieve a strong ENZ response. The ENZ-enhanced optical\u0000Kerr nonlinearity is then investigated in the optimum concentration films of TDBC and HTJSq.\u0000Both nonlinear refractive index and nonlinear absorption coefficient are found to be strongly\u0000enhanced in the ENZ region originating from the coupling of excitonic transition dipoles\u0000associated with large molecular aggregates.","PeriodicalId":410052,"journal":{"name":"Organic Photonic Materials and Devices XXI","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130062306","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}

In addition, EO polymers comprehensively show well compatibility toward other optical components. However, thermal resistance of organic EO polymers still remains challenging for a range of application. To overcome this issue, we have selected norbornene-dicarboximide (NDI) to be utilized as based backbone for our EO polymer. This is because NDI polymer showed excellent properties toward EO applications, such as high glass transitional temperature and good optical transparency. Therefore, by attaching distinct EO chromophores to NDI backbone, both effective EO coefficient and thermal stable EO polymer could be adequately modified. In this study, the polymerisation was performed by ring opening metathesis polymerisation (ROMP). Grubbs catalyst was used to mildly initiate propagation. As the main NDI derivative was linked to cyclohexyl as it offers high thermal properties, NDI with phenyl vinylene thiophene (FTC) chromophore pendant was necessarily investigated to accomplish high chromophore loading density. Moreover, several conditions were considerably performed to afford polymer in high yield and excellent characteristics without unexpected side-reactions. Preliminary results showed that the obtained EO polymer prepared by ROMP at room temperature showed high chromophore loading density over 30% and yield more than 80%. Further investigations remain to be discussed to afford appropriate quality EO polymer for device fabrication.","PeriodicalId":410052,"journal":{"name":"Organic Photonic Materials and Devices XXI","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123680609","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}
