The present invention provides a Molybdenum or Tungsten chalcogenide nanoobject having: (a) an object size comprised from 0.1 to 500 nm, and (b) from 1 to 99% by weight of molecules of formula (I) with respect to the total weight of the nanoobject, wherein: A is —OH; X is selected from: (C-C)alkyl optionally substituted with one or more radicals; a 2 to 20-member heteroalkyl optionally substituted with one or more radicals; and a homopolymer or copolymer comprising a polymeric chain; B is selected from: H, —OH, —NH, (C-C)alkyl, halogen, phenyl substituted with one or more halogen radicals, benzyl substituted with one or more halogen radicals, —C(═O)R, —C(═O)(R), —OC(═O)(O)R, —C(═O)(O), —C(═O)(O)R, —OR, —CH(OR)(OR), —C(OR)(OR)(R), —C(OR)(OR)(OR), —C(OR)(OR)(OR)(OR), —NRR, —NRRR, —C(═NR)(R), —C(═O)(NRR), —N(C(═O)(R)) (C(═O)(R))(R), —O(CN), —NC(═O), —ONO, —CN, —NC, —ON(═O), —NO, —NO, —CHN, —SR, —SSR, —S(═O)(R), — S(═O)(═O)(R), —S(═O)(OH), —S(═O)(═O)(OH), —SCN, —NCS, —C(═S)(R), —PRR, —P(═O)(OH), —OP(═O)(OH), —OP(═O)(OR)(OR), —B(OH), —B(OR)(OR), and —B(OR)(R); provided that when B is —H or (C-C) alkyl, then X is a homopolymer, a copolymer, or a 2 to 20-member heteroalkyl optionally substituted with one or more radicals as defined above. 1.
