Effects of solvents and temperature on spherulites of self-assembled phloroglucinol tristearate
《Frontiers of Chemical Science and Engineering》2020年第3期389-396,共8页Yawen Yao Sabine Rosenfeldt Kai Zhang 
Y.Y.thanks the China Scholarship Council(CSC)for financial support.K.Z.thanks Georg-August-University of Goettingen for the Anschubfinanzierung(Funding for the Promotion of Young Academics of University of Goettingen)and Fonds der Chemischen Industrie(FCI)for the financial support.The authors declare no conflicts of interest.
Herein,phloroglucinol tristearate(PhgTS)was used to study the crystallization process due to its unique symmetric structure containing a benzene ring and three aliphatic chains.Spherulites of crystallized PhgTS from f...
