I have a collegue who is teaching some undergraduate students
about lab techniques, instruments, protocols, etc.  She's interested
in acquiring some cheap organic or inorganic compound whose UV/VIS spectrum
changes with temperature when in aqueous solution, say in the range 0-90 C,
in order to demonstrate the temperature-controlled spectrophotometer.

Any ideas?  This could be anything, as long as it is cheap and safe.

Thanks in advance.  I'll summarize if there's enough interest.
