| dc.description.alternativeAbstract | Highly soluble materials are expected to play for solution process. However, many organic semiconducting materials both small molecule and polymer suffer from low solubility due to secondary bonds. In the past decades, introducing just long aliphatic chain has been used to increase the solubility but there had some drawbacks such as thermal stability and limitation of molecular design. In this study, we introduce the N-substituent chiral side-chains such as phenylethyl, indanyl, tetralinyl into naphthalene diimide (NDI) to increase solubility. The chiral side-chains include chiral-center carbon surrounding four different size and shape groups. Homochiral NDI with identical chiral side-chains has high solubility in dichlorobenzene compare to heterochiral NDI. In dichlorobenzene (DCB), homochiral NDI derivatives exhibit over 1 g/100g of solubility. On the other hand, heterochiral NDI derivatives have poor solubility below 0.4 g/100g in DCB. To investigate the origin, we confirm differential scanning calorimetry (DSC), crystal structure analysis, hirshfeld sulface analysis and free volume analysis. Homochiral NDI has no phase transition and high melting temperature compare to N,N'-Bis(1-hexyl)naphthalene-1,4,5,8-tetracarboxylic diimide (NDI-C6) with hexyl alkyl side-chain. Homchiral NDI exhibits asymmetric shape due to symmetric breaking side-chains. It has large free volume compare to heterochiral NDI. Therefore, introducing homochiral side-chains as solubilizing group are notable molecular design strategy for highly soluble materials. | - |
