摘要
4-hydroxy-4'-nitroazobenzene(NHA)and4-amino-4'-nitroazobenzene(DO3)werepreparedrespectivelyfromp-nitrophenylamineasaprecursorcompound.Twokindsofdopedorganic/inorganichybridnonlinearoptical(NLO)materialscontainingNHAandDO3weresynthesizedbySol-Gelprocess.ThepreparationandpropertiesoftwoNLOmaterialswerestudiedandcharacterizedbyFTIR,1H-NMR,UV-VIS,SEM,DSCandSHGmeasurements.TheresultsshowthatthemaximumdopingamountsofNHAandDO3intwodopedhybridNLOmaterialsare7.2(wt)%and11.3(wt)%respectively,andthecorrespondingsecond-orderNLOcoefficients(d33values)are2.91×10-8esuand6.14×10-8esu.TwodopedNLOmaterialshaverelativelygoodRTstability,after90daysatRTthed33valuescanmaintainabout85%oftheirinitialvalues,butafter10hat100℃canonlymaintainabout50%oftheirinitialvalues.Inthisreport,thereasonsforhigh-temperatureinstabilityofdopedmaterialswerediscussed,andthepossibleimprovementswerealsosuggested.
