my hope? just want to finish all of this a.s.a.p. but my research motivation is to find something new about liquid crystal properties

i'm trying to improve my compound's color. they're purple and orange, temperature dependent. but, still not enough for my thesis

what's that?

oh no no no...it's not about the display, i'm focusing on the synthesis part. it's boring...

hmmm...it's about the pitch. LC has a helical structure, and when the temperature changes, the pitch changes

and LC only reflect the light with wavelength equal to the pitch length

yes you're correct! voltage can also change the pitch length. magnetic field also...

the molecules align at a slight angle to one another, external energy will change the alignment of the molecules (called mesogen).

wow!i have no idea about that. i'm studying chemical engineering right now. but i don't think there is any 'engineering' part in my research
