Record 1 of 2

Record #:	1171
Class ID:	2.8
Class Name:	polyacetylene
Polymer:	poly(phenylacetylene)
Matrix:	trans-2-[3-(4-tert-butylphenyl)-2-methyl-2-propenylidene]malononitrile (300364-84-5)
Salt:	AgOCOCF₃ (AgTFA)
Solvent:	dichloromethane( CH₂Cl₂)
Recipe	Samples for MALDI-TOF mass spectrometry were prepared from a CH2Cl2 solution by mixing the sample (10 mg/mL) in a volume ratio of 1:100:1 with the matrix trans-2-[3-(4-tert-butylphenyl)-2-methyl-2-propenylidene]malononitrile (20 mg/mL) and AgOCOCF3 (2 mg/mL), respectively.

Record 2 of 2

Record #:	954
Class ID:	3.1
Class Name:	conjugated polymer
Polymer:	poly(phenyl acetylene)
Matrix:	DCTB (trans-2-[3-(4-tert-butylphenyl)-2-methyl-2-propenylidene]malononitrile (300364-84-5)
Salt:	silver trifluoracetate (AgTFA)
Solvent:	CH₂Cl₂
Recipe	Samples of MALDI-TOF mass spectrometry were prepared from a CH2Cl2 solution by mixing the sample [10 mg/mL using the polymers purified by column chromatography (silica gel, toluene as eluent) to remove a trace of Pd], DCTB (trans-2-[3-(4-tert-butylphenyl)-2-methyl-2-propenylidene]malononitrile, 20 mg/mL), and AgTFA (silver trifluoroacetate, 2 mg/mL) in a ratio of 2:1:1.
