During the long years of tearching that I have spent in VoNguyenGiap Gifted High School I have had the personal and professional support of numerous people that I would like to acknowledge. Without their help and support, this journey looked like it will never end.
I would like to start by thanking to my leader, Hoang Thanh Canh, whose encouragement, guidance and support from the beginning to the end enabled me to broaden knowledges of this subject. I appreciate him for helping me to try my best. In addition to my mentor, there are numerous people who have contributed to this work whom I would like to mention by name. I would also like to thank all members of Chemistry group: Dang Ba Hung, Lam Mau Tai, Bach Ngoc Chinh, Nguyen Thi Huong, Cao Thu Hien, Duong Le Hong, Luu Vu Diem Hang for their immense help and support throughout this work, especially Quangbinh high school for gifted students that supports a good condition for making this dream possible and finally a reality. I also want to thank all my students, 12 Hoa for making life outside of the lab enjoyable.
Finally, I would like to thank my family, especially my wife, Le Thi Thanh Bong, my lovely daughter Tu Bao Tram Anh and son Tu Sy Tien, and my parents for being with me every step of the way. This would not have been possible without their support. I dedicate this work to


Conductive polymer is a kind of attractive material since it was invented in 1977. After over three decades, it is still an emerging research area due to its wide application in light-emitting device, supercapacitors, electrochromic devices and organic photovoltaic cells. So that the growing demand for organic conjugated material for their use in semiconductor decvices, for electronic and optoelectronic technologies, low band gap conjugated polymer are among the most promising material. In addition, it can be easily tailored by rationally designed and synthesized. As far as its synthesis methods are concerned, it mainly includes chemical oxidation polymerization, electropolymerization and photo-polymerization but recently some groups make arduous efforts to pay much attention on solid-state polymerization (SSP), which appeared early in the 1960s. This method deserves much attention due to its special features such as solvent free and oxidant or additional potential free, so this method is necessarily required through traditional methods. Besides, solid-state polymerization is a commonly practiced technique to obtain high weight crystalline polymers such as commercial poly(ethylene-terephtalate) and poly(aryl carbonate). The technique of method involves heating the monomer crystal below their melting point without using any catalyst or solvent. On the other hand, the physical state of the monomer is very important in determining both the reaction kinetics and the morphological, crystallographic and molecular structures of the resulting polymer. Till now, only a few examples of thiophene derivatives which are suitable for SSP were successfully realized since pioneer work which was done by Wudl and co-worker, who first successfully made poly(3,4-ethylenedioxythiophene) (PEDOT) with spontaneous SSP in 2003.
