試題 :
1.For the electronic absorption spectra, please answer the following questions,
(a) please draw the absortion spectrum of a typical semiconducting polymer
(absorption vs wavelegth with scale) (b) describe how to determine the IP,EA
and band gap of semiconducting polymers. (total 10 points)
2.Please list at least four possible sturctural factors for tuning the
electronic properties (IP,EA,or band gap) of conjugated polymers and give
each factors an example. (20 points)
3.(a)Please give explanation on the order of Eg,IP, and EA in the PPV
derivatives of the attached Table in the next page.(You should not use
the polymer as an example for problem 2,you should use PPV as the parent
polymers and compare the properties of PPV with others,15 points)
(b)Suppose the electronic properties of poly(thiophene vinylene),
poly(pyrrole vinylene),and poly(quinoxialine vinylene) are unknown,
please comment on the order of electronic properties with PPV.
(10 points)
4.(a)The bandgap of polythiophene is around 1.8~2.0eV. Please suggest at least
two strategies to reduce Eg, and explain them; (b)If you want to increase
Eg of polythiophene, what kind of structural modification will you make?
(total 20 points)
5.(a)Please compare the band gap of poly(polythiophene-alt-quinoxaline)(PTQX)
with its homopolymers of poly(thiophene) and poly(quinoxaline).
(b)If you want to further reduced the bandgap of PTQX, what approach will
you used? (total 20 points)
