Confirmation of Synthesis of Organic Functional Materials Using Benchtop MALDI-TOF MS

Introduction

The Matrix-Assisted Laser Desorption/Ionization Time-of-Flight Mass Spectrometer (MALDI-TOF MS) has the advantage of simply and quickly obtaining molecular weight information on diverse types of samples from low molecular to macromolecular materials. MALDI-TOF MS instruments are widely used in confirmation of the molecular weights of synthetics and natural substances in the field of R&D and quality control. In comparison with LC-MS and other types of mass spectrometers, MALDI-TOF MS enables use of diverse solvents, is quick and simple in optimizing acquisition parameters, and detects mainly the peaks of singly charged ions (one component = one peak), even with samples having large molecular weights. Due to these advantages, it is possible to confirm synthesis of organic functional materials such as organic dyes, organic light-emitting diode (OLED) materials, and organic photovoltaic cells simply and quickly. Here, we introduce examples of measurement of various types of organic functional materials using a benchtop MALDI-TOF MS.
